Integrated Storm Water Management (iWATER)


Climate change has led to more frequent and intense storm and rainfall events along with increased flooding, storm water runoff, and soil erosion. The Baltic Sea region is estimated to face more frequent and heavier rainfalls, so there is the need to develop urban planning strategies dealing with greater volume and velocity of storm water. At the same time, urban areas are densifying and land is more covered with sealed surfaces. iWater - Integrated Storm Water Management project aims to improve the urban planning in the cities of the Baltic Sea Region via developing integrated storm water management system. The project idea is to create higher quality, cleaner and safer urban environment and increase urban sustainability. Common guidelines and tools of integrated storm water management will be developed in the partnering cities with the involvement of local stakeholder and interest groups.

The Integrated Storm Water Management Toolbox, created in the iWater project, provides both general and detailed information on urban stormwater management approaches and tools.
